With a unique antimicrobial dispersion varnish suitable for a wide range of applications and packaging types
As the new and preferred sales partner for Varcotec’s innovative Lock 3 technology, German firm Siegwerk is expanding its range of packaging inks and varnishes with a unique antimicrobial dispersion varnish suitable for a wide range of applications and packaging types.
Siegwerk, one of the leading suppliers of printing inks for packaging applications and labels, and Varcotec, a specialist for technically sophisticated overprint varnishes made for the printing industry, have entered into a distribution partnership for Varcotec’s Lock 3 antimicrobial coating technology in the EMEA region (Europe, Middle East and Africa).
This innovative dispersion varnish is the first of its kind, and was developed in cooperation with a spin-off company affiliated with the University of Regensburg, Germany. The antimicrobial effectiveness of this product has already been confirmed by several independent testing institutions.
The water-based overprint varnish Lock 3 allows for permanent, independent disinfection of the printed surfaces under ambient room lighting or in open daylight. Lock 3 contains a specially patented substance, taking advantage of the principle of photodynamics: the photocatalyst is activated by visible light and transfers the energy thus absorbing the surrounding oxygen. This process creates so-called singlet oxygen, efficiently killing germs by oxidizing their shells.
